St. John the Baptist has been located around Malbork since at least the 13th century, having been destroyed and rebuilt on several occasions. The current building was like so many other old ones in the town rebuilt at the end of the Thirteen Year War in 1468, although the current wooden bell tower dates from the 1520s. Always a Catholic church, the interior, most of which dates from extensive conservation work between the wars, is rather plain. Outstanding features include a medieval sculpture of St. Elizabeth of Turin and the neo-Gothic altar.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
